Figure legends
Figure 1 Geographic distribution of MRC occurrence and
background-weighted points. Background-weighted points were allocated
based on a probability distribution of a density raster of training
occurrence points.
Figure 2 Habitat suitability map of the tuned-up models derived
from random (Rndm) and background weighting (BkWt) schemes.
Figure 3 Variation of sensitivity (Sens); the proportion of
correctly predicted presence data, and specificity (Spec); the
proportion of correctly predicted pseudo-absence data, across a gradient
of suitability thresholds. Dashed lines indicates test data. Rndm:
random and BkWt: background weighting schemes. The black diamonds
indicate the corresponding threshold of the 10 percentile suitability of
the training dataset.
Figure 4 Response curve of the explanatory variables derived
from models obtained based on the random (top) and background weighting
(bottem) schemes. Models were fitted in biomod2 package.
